DATS suppressed cancer cells proliferation and induced cell cycle arrest accompanied by an increase in the expressions of cyclin A2 and cyclin B1 in SGC-7901 cancer cells.
In this study, HT-29 and other diverse panel of cancer cells were used to demonstrate that both aspirin and its primary metabolite, salicylic acid, decreased cyclin A2 (CCNA2) and CDK2 protein and mRNA levels.
Although overexpression of cyclin A2 is reportedly an indicator of a poor prognosis of various malignancies including endometrial carcinoma, its molecular mechanism remains undetermined.
This analysis predicts that cancer cells manifesting a stem cell-like expression profile of a death-from-cancer signature would exhibit the following features: a concomitantly increased expression of certain members of inhibitor of apoptosis protein (IAP) family (Survivin and XIAP); activation of mitotic spindle check point proteins (BUB1, BUB3, KNTC2, Mad2, PLK1, PLK4, STK6/Aurora A); and elevated levels of certain cell cycle control/marker proteins (CCNB1, CCNB2, CCND1, CCNA2, CDC2, CDC25, Ki67, USP22).
